TOOL FOR RAISING SUCKER-RODS FROM WELLS.

SPECIFICATION forming part of LettersPatent No. 299,254, dated May 27,1884. Application filed December 12, 1882. Renewed March 19, 1884.(Model.)

To all whom it may concern.-

Be it known that I, MARVIN NEWTON, of Knapp s Creek, in the county ofGattaraugus and State of New York, have invented a new and Improved Toolfor Raising Sucker-Rods from Wells, of which the following is a full,clear, and exact description. I

With the tools heretofore employed for fishing sucker-rods from wells itoften occurs that they cannot be passed down over the rods on account ofthe straps being broken and bent outward against the tubing, and suchtools will also frequently lose their hold and the rod drops back intothe well.

The object of my invention is to provide a tool that shall be reliableunder all circum stances.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal section of my improved tool, showing the sameas attached upon a pump-rod. Fig. 2 is'a side elevation of the same,partly sectional. Fig. 3isahorizontal section of the tool.

A is the tool, consisting of a tube or ferrule of suitable length, andof a diameter for pass ing freely-down over the rod and within thetubing. The tube is formed of thin sheetst-eel. and made with a slit, a,at one side, which slit is normally retained slightly open by the springof the metal, so that it allows the lowerend of the tube A to springinward when passing the joint of the tubing, and then spring outwardagain in order to fill the tubing. The lower end of the tube is madewith a level, I), which forms a point at one side, and a cutting-edge.\Vithin the tubing, at or near the lower end, is a fiat spring, a, whichis attached at one of its ends and projects upward within the tubing,the spring being bent outward toward the center of the tube. At

its upper end are straps d d, to which the rod eis connected forlowering and raising the tube, and to this upper end are also connectedspring-arms f f, which are attached at opposite sides of the tube, andproject inward over the top of the same, their ends being formed withchisel-edges.

In using the tube, it is passed down within the well-tube and around thepump-rod, and in case the straps of the rod are bent outward against thetubing, or if the rivets project to interfere with the downward movementof the tool, its lower edge, being formed as a cutter and of steel, willcut them off. The tool is passed down until the spring-arm c, at itslower end, passes beneath the collar on the pump-rod at a point wherethe rods arescrewed together. As soon as the spring 0 passes this collarit will spring outward beneath the same, so that when the tool is againraised it will bring the rod up with it. The spring 0 extends far enoughup into the tube A to prevent the rod from springing out when the toolleaves the upper end of the tubing. Holes 9 are provided in the tube A,for the insertion of a small iron rod to move the spring back to releasethe pump-rod. In case the pumprod is broken so far from the joint thatthe spring 0 will not reach the collar, the end of the spring 0 willenter the wooden rod sufficiently far to hold it and allow of its beingraised; but in case the spring-c should fail to hold, the twospring-arms f at the upper end of the tube A will enter the rod and holdit securely.

At B is represented a sucker-rod within the tool attached thereon.

I am aware that diagonal cuts at the lower end of tube and a sharpbeveled end opposite sprihgarrns on a pump-rod-raising tube and oppositestraps on raising-tube, and attached to lifting-rod, are notsubstantially new; but

WVhat I do claim as new and of my invention is l. A tube for raisingsucker-rods, made of spring metal, and with the slit a, whereby thelower end of the metal will spring outwardly when passing a joint, asdescribed.

2. A tube for raising the sucker-rods of a pump, provided with the holes9 and spring 0, arranged with respect to each other to allow theinsertion of a rod for releasing the spring from the pump-rod, asdescribed.
